Defunct hydroelectric dam
About the Project
Eklutna Dam—located in a narrow canyon about 25 miles northwest of Anchorage, Alaska near the Native Village of Eklutna—was built in the late 1920’s as part of the state’s first hydroelectric project. The project was decommissioned in the 1950’s after sediment filled the reservoir, and dam maintenance ceased.
The Eklutna Dena’ina people built their village at the mouth of the Eklutna River, which empties into the Knik Arm of the Cook Inlet and once hosted prolific salmon. For decades, however, the 70 foot- high Eklutna Dam blocked salmon runs for five species of Pacific salmon (king, sockeye, silver, pink, and chum), degraded habitat, and led to a fisheries decline throughout the Eklutna River system.
The Eklutna Dam was removed in 2018. Removal of this dam, located on lands owned by Eklutna, Inc., an Alaskan regional native corporation, is the first step towards restoring river functions and traditional practices in the Native Village of Eklutna. Just upstream of the dam site lies Eklutna Lake, from which two hydropower facilities divert water for energy, releasing little water into the river. The next phase of the project focuses on implementation of fish mitigation measures required under a regulatory agreement with the hydropower companies to ensure water is released from Eklutna Lake in amounts sufficient to sustain healthy fish populations.
FACTS AT A GLANCE
